It is greatly perplexing to think some army would choose to build a bridge that may take sevaral years to cross the shallow sea , as deep as 3 ft to 12 ft throughout the 30 kilometer span.
Any army with the least common sense would have built ships, probably not as complex as ocean going ships as they are not nessasary as the waters here are vey shallow. even river crossing boats would have been enough.
So what prompteed the great Rama to build the bridge no one is asking.The matter of he comming to Dandakaranya by crossing many rivers is well known by the so called historians, who think puranas are absolute history. he did not build a single bridge across any river he crossed during his journey to the south , but chose to travel by boats.
So what may be true is that the sethu may be existing there eternally even before Rama arrived at Daniskodi, and Rama may be the first one to identify the submerged coral reefs during his reconnesense of the sea.
Rama probably being a wise general used it by putting some boalders on the top of the submerged sethu, in the process saving the time rather than building the ships.
And the next question we should ask ourselves is if we have to go for the sethusamudram project. Well if sethusamudram project costs say some 20k crores, and the allignment costs us more than 30k corese, then we need not change the allignment.Ous is a poor nation the extra money saved can be utilised in poverty eradication schemes rather than wasting the money u
